Add many PRs since release 2023.04

[mebenn]

release-notes/latest-changes Included only some PRs since 2023.04; but needs editing and PRs before 2023. Might be able to help to do this, but require pointers as to which PRs to include/exclude. There have been many PRs since the release a couple of days ago; but many of these are forced rebuilds; but many are relevant, i.e., new packages etc.

We could easily automate this with a script; but we wouldn't want to include all PRs, just the relevant ones. But how do we figure out which PRs are relevant? Maybe some keyword in the title of the PR?
